#
# SYNOPSIS
#
#   AC_TRY_RUN_JAVA
#
# DESCRIPTION
#
#   AC_TRY_RUN_JAVA attempt to compile and run user given source.
#
#   *Warning*: its success or failure can depend on a proper setting of
#   the CLASSPATH env. variable.
#
#   Note: This is part of the set of autoconf M4 macros for Java
#   programs. It is VERY IMPORTANT that you download the whole set,
#   some macros depend on other. Unfortunately, the autoconf archive
#   does not support the concept of set of macros, so I had to break it
#   for submission. The general documentation, as well as the sample
#   configure.in, is included in the AC_PROG_JAVA macro.
